Question

Find the ratio of the following: $500\mathrm{ml}\mathrm{to}2\mathrm{litres}$

Answer 1

We have,

$\begin{array}{rcl}\mathrm{Ratio}\mathrm{of}500\mathrm{ml}\mathrm{to}2\mathrm{litres}& =& \frac{500}{2\times 1000}[\because 1\mathrm{litre}=1000\mathrm{ml}]\\ & =& \frac{500}{2000}\\ & & \mathrm{Dividing}\mathrm{numerator}\mathrm{and}\mathrm{denominator}\mathrm{by}\mathrm{their}\mathrm{HCF}\mathrm{i}.\mathrm{e}.500\\ & =& \frac{1}{4}\\ & =& 1:4\end{array}$

Hence, ratio of $500\mathrm{ml}\mathrm{to}2\mathrm{litres}$ is $1:4$.
